Abstract
Compact optical channel dropping filters incorporating side-coupled ri ng resonators as small as 3 mu m in radius are realized in silicon tec hnology. Quality factors up to 250, and a free-spectral range (FSR) as large as 24 nm are measured. Such structures can be used as fundament al building blocks in more sophisticated optical signal processing dev ices.
